Chime pro Installation - Tone problem

Installing the chime pro is a pain! Eventually if found my wi-fi after claiming I was using the wrong password and there was no signal!Anyway, all went well until I tried to change the Chime seyying.I got “Hmm, something went wrong. Sorry about this, try again”Every time I try again I get the same message.Also the Blue light flashes and I have to start all over again!!!I have another chime Pro but I get the same problem on that!!Any help will be most appreciated.The old chimes were great!!
